CORAL GABLES (CBSMiami) – A South Florida man inadvertently put himself behind bars – busted for child porn after apparently he just handed over the evidence.

With a disgusted look on her face, Miami-Dade Judge Mindy Glazer read the details of the 11 child porn charges against 55-year-old Orlando Chang.

“Seven, 9-year-old children depicted in various sexual positions engaging in sexual acts with unknown adults…” Judge Glazer read from the court documents.

Chang was just picked up on a warrant at his apartment in Little Havana on Monday.

According to investigators, this stems from an incident last summer when Chang went into this Metro PCS store on Miracle Mile in Coral Gables to swap out phones and asked for help.

“The allegations are that he went to the Metro PCS store wanting information from his old phone transferred to his new phone,” said the prosecutor. “The employee saw these images.”

According to the warrant, the store employee immediately called police when he noticed extremely explicit photos of a girl as young as 7.

When police questioned Chang he reportedly made a very disturbing statement that “…the images were sent to him by the child’s mother.”

Judge Glazer took everything into account when she set bond.

“Counts 1 through 11 will be $7,000 each,” Judge Glazer said.

While investigators are not going on camera, talking about specifics, the Miami-Dade State Attorney’s Office said, in general, the big concern in cases like this is what happens in situations where no one discovers the explicit photos.

“The people who do these things tend to end their excitement on imagery and always want more and they move further that’s the basic nature of a sex offender,” explained Ed Griffith from the State Attorney’s Office.
